Wireless not working, but ethernet does

Hi guys ,I am facing the weirdest problem . when I m trying to connect my laptop using wifi , my modem get rebooted ..all light gets off (DSL,WLAN,Internet) automatically . is it any malware or what ? I have updated my BIOS , my wireless driver ..but nothing worked .nd when I m connecting using ethernet its working fine , modem working smoothly .

Please let us know the message you see when you try to establish a wireless connection to the internet. Is your computer able to detect wireless networks? What version of Windows are you using and what is the model and name of the wireless router?

Thanks and regards,

Make sure the modem and router are rebooted. Or power cycle both. Turn off power wait 30 seconds then power on first the modem then wait 30 seconds then power on the router. If your using all-in-one modem with router then just power the one device on and off for 30 seconds.
